"Llamas exhibit behaviors similar to their wild predecessor, the guanaco (Lama guanicoe), and are known to defend territories and family groups (Franklin and Powell 1994). Llamas are considered most effective against canine species"(615)

"Guard llamas provide some advantages over guard dogs, including 1) greater longevity, 2) fewer training requirements, 3) faster acquisition of guardian status, 4) fewer special management considerations involving food and maintenance, and 5) compatibility with other depredation control techniques."(615)

"[During the study], three hundred twenty sheep were reported lost to predators, with lambs comprising 85% of these losses…. Dog, fox, and coyote predation accounted for 92% of all sheep losses to predators reported during the study."(616)

"Treatment flocks lost 42 sheep to predators in SGS1 and 35 in SGS2, whereas the control group lost 128 sheep in SGS1 and only 32 in SGS2."(616)

"Treatment flocks appeared to have similar proportions of flocks with loss during SGS1 and SGS2, whereas the proportions of control flocks with loss were greater in SGS1 and dropped to levels similar to treatment flocks in SGS2."(617)

"After having a llama with their sheep for 20 months, 9 of 20 (45%) producers claimed the llamas were very effective at reducing predation on their sheep, 9 (45%) rated their llama as effective, none claimed no opinion, and 2 (10%) felt their llama was not effective."(618)

"in survey 2, 67% (of producers using guard llamas) indicated less reliance on other depredation control methods and made fewer calls to their WS specialist."(618)

"Initially, the decline (72%) in numbers of lambs killed by canine predators between 1996 and 1997, especially among producers without llamas, lacked explanation. This resulted from a marked decline in the fraction of producers experiencing greater losses. In 1996, over half the flocks in this study reported lamb predation losses >2%, but in 1997 <10% of flocks were in this category."(619)

"A surprising number of reports involving llamas chasing coyotes, foxes, or domestic dogs were received. Additionally, several producers observed llamas ‘gathering’ the sheep and placing themselves between the sheep and an intruding canine."(620)

"Although llamas quickly bond with sheep, most prefer to associate with other llamas if given the opportunity. Several producers reported their llamas jumped out of their pastures when another llama was visible. Moving them to pastures away from other llamas solved these problems."(620)
